Objective: The purpose of this study was to explore the effect of our rooming-in protocol on the need to treat withdrawal in the opiateexposed newborn. Methods: We reviewed the medical records of mother-infant dyads born between October 1, 2003, and December 31, 2006, who received care in our rooming-in program. Data on the type of drug used by the mother, maternal methadone dose at delivery, morphine treatment of the baby, and perinatal outcome were considered. Results: We found a significant positive relationship between maternal methadone dose at delivery, "other opiate" use, and breastfeeding and the need to treat the neonate for withdrawal. We also found the maternal methadone dose at delivery to be related to the duration of pharmacological treatment of the neonate. Conclusion: Our findings suggest a role for our rooming-in program in mitigating the relationship between maternal methadone dosage and the need to treat opiate withdrawal in the newborn. Consideration of the role played by the mother-infant dyad model of care needs to be considered in future studies. © 2012 Society of Obstetricians and Gynaecologists of Canada. Source

Breast cancer risk estimations are both informative and useful at the population level, with many screening programs relying on these assessments to allocate resources such as breast MRI. This cross-sectional multicenter study attempts to quantify the breast cancer risk distribution for women between the ages of 40 to 79 years undergoing screening mammography in British Columbia (BC), Canada. The proportion of women at high breast cancer risk was estimated by surveying women enrolled in the Screening Mammography Program of British Columbia (SMPBC) for known breast cancer risk factors. Each respondent's 10-year risk was computed with both the Tyrer-Cuzick and Gail risk assessment models. The resulting risk distributions were evaluated using the guidelines from the National Institute for Health and Care Excellence (United Kingdom). Of the 4,266 women surveyed, 3.5% of women between the ages of 40 to 79 years were found to have a high 10-year risk of developing breast cancer using the Tyrer-Cuzick model (1.1% using the Gail model). When extrapolated to the screening population, it was estimated that 19,414 women in the SMPBC are considered to be at high breast cancer risk. These women may benefit from additional MRI screening; preliminary analysis suggests that 4 to 5 additional MRI machines would be required to screen these high-risk women. However, the use of different models and guidelines will modify the number of women qualifying for additional screening interventions, thus impacting the MRI resources required. The results of this project can now be used to inform decision-making groups about resource allocation for breast cancer screening in BC. ©2013 AACR. Source

Objective To describe the characteristics of a national cohort of pregnant women on methadone maintenance treatment (MMT) and to provide treatment outcome data for integrated care programs. Design Retrospective chart review. Setting Three different integrated care programs in geographically distinct cities: the Toronto Centre for Substance Use in Pregnancy in Toronto, Ont; the Herzl Family Practice Centre in Montreal, Que; and the Sheway clinic in Vancouver, BC. Participants Pregnant women meeting criteria for opioid dependence and attending an integrated care program between 1997 and 2009. Women were excluded if they were on MMT only for chronic pain. Main outcome measures Patient demographic characteristics, concurrent medical and psychiatric disorders, and substance use outcome data. Results A total of 102 opioid-dependent pregnancies were included. The mean age was 29.7 years and 64% of women were white. Women in Montreal were more likely to have partners and had fewer children. Differences in living and housing situations among the sites tended to resolve by the time of delivery. Almost half of this cohort tested positive for hepatitis C. Women had a high prevalence of depression and anxiety across all sites. Half of this cohort was on MMT before conception and for the other half, MMT was initiated at a mean gestational age of 20.7 weeks, resulting in a mean dose of 82.4 mg at delivery. At the first visit, polysubstance use was common. Prescription opioid use was more frequent in Toronto and heroin use was more prevalent in Vancouver and Montreal. For the entire population, significant reductions were found by the time of delivery for illicit (P < .001) and prescription opioids (P = .001), cocaine (P < .001), marijuana (P = .009), and alcohol use (P < .001). Conclusion Despite geographic differences, all 3 integrated care programs have been associated with significant decreases in substance use in pregnant opioid-dependent women. Source

Objective: We sought to quantify the accuracy of estimating gestational age by reported last menstrual period among women seeking surgical abortion. We observed that women seeking surgical abortion underestimated their gestational age when making the appointment, leading to poor allocation of resources. This tendency to underestimate has not previously been reported and differs from the accurate dating reported among women choosing either medical abortion or continuation of the pregnancy. Methods: We performed a retrospective review of randomly selected medical records for women with abortions scheduled at 9 to 20 weeks' gestation (n. =. 415) at two clinics in Vancouver between 2002 and 2008. Results: The mean gestational age calculated by menstrual dates (14.3, SD 3.9) was 1.2 (95% CI 0.9 to 1.4) weeks less than that calculated by ultrasound (15.5, SD 3.4) (P. <. 0.001). Greater gestational age was associated with a larger discrepancy (r. =. 0.192, P. <. 0.001). Variables other than gestational age (maternal age, parity, previous abortions, illicit drug use, and contraceptive method at conception) were not significant predictors of inaccurate menstrual dating. Conclusion: Women seeking surgical abortion for pregnancies of 9 to 20 weeks underreport gestational age by an average of 1.2 weeks using menstrual dating. We found that women who intended to continue with their pregnancy overestimated their gestational age, those seeking very early abortion estimated most accurately, and those seeking surgical abortion at more than nine weeks had a clinically significant underestimation of their gestational age. Clinicians referring and counselling women who are considering surgical abortion must facilitate timely access to clinical or ultrasound dating of their pregnancy. © 2011 Society of Obstetricians and Gynaecologists of Canada.

Background: The benefits of social support in post-surgical recovery are well documented; social support decreases preoperative stress and postoperative recovery time. However, a paucity of studies have examined the effect of social support in the context of pregnancy termination. This study is the first to examine the effect of postoperative accompaniment from the patient, support person and nurses' perspective. Study Design: This study was carried out in two phases. In Phase I, no accompaniment was allowed in the post-anesthesia recovery room (PAR); in Phase II, accompaniment was permitted. All participants completed pre- and postoperative questionnaires. Results: The perception of accompaniment was overwhelmingly positive in patients and support people. Patients in Phase II demonstrated a high (over 95%) acceptance of accompaniment in the recovery room. It was found that 96.8% reported they would choose to be accompanied in the recovery room again if they had to have another abortion. Support persons felt very strongly that their presence was helpful to the patient. The decrease in pre- to postoperative anxiety levels was significantly greater in those women who were accompanied. However, overall, nurses demonstrated a negative attitude towards accompaniment in the recovery room. Conclusion: In summary, the presence of a support person in the PAR was perceived in a positive manner by patients and support people. However, the reasoning behind the negative opinion of nurses requires further study before PAR accompaniment can be considered a possibility in the context of pregnancy termination. © 2011 Elsevier Inc.
